IMPROVEMENT'IN THE MANUFACTURE OF RUBBER-COATED CARRIAGE-TRIMMING-Si TheSchedule referred to in these Letters Patent and making part of thesame.

To all whom it may concernf the door, to facilitate the closing ofthedoor;

Figure 2, aside view of the latch-handle; I Figure 3, the metal portionof the latch-handle;

.and in Figure 4, a transverse section of the handle on line so: of.fig. 2.

This invention relates to an improvement in carriage-trimmings,generally used upon theinterior of carriages, the object being .to makethese articles stronger, cheaper,better, andmore ornamental than hasheretofore been done and i It consists in coating metalliccarriage-tlzinnnlngs and similar articles wholly or in part-withacombination of difi'erent-colored India rubber, or any of its alliedgums, which may be molded upon the articles, and subsequently hardenedbythccuring-process.

Heretofore these articles have been made entirely of metal and plated,or partly of metal, with the parts of other material, as pearl, ivory,8m, fitted into sockets formed on the parts.

In my invention Iform the articles according to the desired shape, as,-for instance, the handle in fig. 2. The spindle-socket A and handle,down to about the point a,I form in the usualmanner. The remainingportion -I form slightly reduced from the required size, as seen in fig.3.

I then coat the surface with prepared gum, prefer ring India rubber,which is compounded to make what is known as hard rubber? To give a moreornamental appearance to the haudle, and in imitation of choice woods, Icombine different-colored gums, as, for rosewood, take red and black,and mingle the two, so as to indicate the grain of the wood, as shown bythe shades of light and dark in the figures. v

The gum laid upon the surface of the handle, the handle isthen placed insuitable dies, and the gum pressedhard thereon, then cured in the usualmanner. The articles thus produced are strong as the metal itself, andthe surface of the gum, highly polished,

.gives' to the articles an appearance of elegance which cannot beproduced in any other way.

Other articles, as the-pull-loop, fig. 1, are formed in substantiallythe same manner, the part below the, shoulder a being prepared andcoated as described for the handle.

From this description, it will be evident'to those skilled in theaitthat other articles may in like manner be coated. i

The cheapness of this construction will be apparent,

when it is considered that the whole'portion of the article below thepoint a In ust be made solid, of such ornamental material, and the partsmechanically secured together, whereas, in this construction, the metalis continued nearly the full size throughout the extent of the article,and the metalis cheaper than any ornamental material suitable for suchwork.

In combining difl'ereut colors to produce the desired eflect,.somedegree of care must be exercised in the combination of the gums, as, forinstance, in rosewood, in which the base is red, the black should belaid in imitation of the grain, and care should be exercised that thered, when cured, should be the proper tint, and to produce such colors,those skilled in the working of gums will readily understand.

" I claim as my i nvention-- As a new article of manufacture,carriage-trimmings,

coatedwholly or in part with India rubber'or similar gums, prepared andapplied snbstantiallyin the manner herein set forth.- I
